Hookworm , the life of this parasitic nematode begins outside the human body, it enters the human body through contaminated water, fruits and vegetables. Hookworm larvae grow in people's internal organs, they attach to the walls of the host's internal organs, suck the host's blood, and sometimes cause the host to develop anemia called enterocosis. Symptoms: weakness, abdominal pain, nausea, diarrhea, anemia.
Roundworms are the most parasitic nematodes that parasitize human internal organs and can grow to 15 to 35 cm long. Roundworms are transmitted by feeding. Ascaria eggs hatch, they quickly pierce the walls of a person's internal organs and enter the bloodstream. Through the bloodstream into the lungs, then is coughed up and swallowed, and returned to the internal organs again. Symptoms: fever, fatigue, allergies, rash, vomiting, diarrhea, nervous problems, wheezing, and cough.
Tapeworms spread by contaminating food, attaching to the host's internal organs through "hooks" on the head. Tapeworms mature in 3 to 4 months. It can parasitize the human body for up to 25 years. Tapeworm eggs can be excreted through feces, can survive in plants, and then be eaten by cattle, pigs, or passed on to humans. Symptoms: nausea, vomiting, inflammation of internal organs, diarrhea, weight loss, dizziness, cramps.
Ben's Vulcellum, a mosquito that carries this parasite, releases it into the human bloodstream by biting humans. The larvae of Ben's Vitex enter the lymph glands, especially those in the legs and reproductive areas, and it takes up to 1 year to grow into an adult. They can cause tropical diseases and sometimes elephantiasis. Symptoms: fever, chills, skin infections, lymphatic pain, thickened skin, swelling.
Giardia lancosa is a native parasite with flagella. It parasitizes and multiplies in human internal organs and can cause Giardiasis. This parasite causes inflammation and other damage after the human internal organs have landed, weakening the ability of the internal organs to absorb nutrients and causing diarrhea. This parasite is found in drinking water. Symptoms: diarrhea, nausea, abdominal pain, weight loss, hiccups that smell of rotten eggs.
Dysentery amoebic , it is a single-celled organism, which can cause amoebic disease. This parasite mainly infects humans and other primates. It may be present in water, in humid environments and in soil, and may contaminate fruits and vegetables. Dysentery amoeba is transmitted through feces. Unlike the malaria parasite, it is more likely to cause death than other protozoa. Symptoms: abdominal pain, weight loss, weakness, diarrhea.
Toxoplasma gondii, a common crescent-shaped parasite that attacks the central nervous system of a person. People can get the parasite by eating undercooked meat or holding infected pets. Most people have been infected with this parasite, showing its antibodies, but few have shown symptoms. People with weaker immune systems are more susceptible to toxoplasma gondii infection, and pregnant women infected with toxoplasma gondii fetuses are severely affected. Symptoms: fever, chills, weakness, headache.
Pinworms are common human parasites that can cause pinworm disease. Adults and females can grow from 8 mm to 13 mm. The posterior part of the pinworm is long needle-shaped, hence its name. Pinworms mate through traumatic insemination, and they make their home in the host's internal organs, but unlike most parasites, they do not enter the bloodstream and cannot survive in other parts of the body. Pinworms lay eggs outside the body, which causes a feeling of tickling in the person, and the larvae spread through human hand scratching. Symptoms: inflammation and itching.
Schistosomiasis These small bugs parasitize the blood of the host, which can cause the host to develop schistosomiasis. They live in water, and when people come into contact with contaminated water, schistosomiasis puncture their skin. This parasite can cause inflammation and damage organs, especially the liver. Adults can parasitize human hosts for decades and may not show any symptoms for years. They leave their hosts with their bowel movements and spend the rest of their lives in the snail host.
Symptoms: fever, pain, cough, diarrhea, swelling, lethargy.
Scabies, this parasite is transmitted through physical contact. Female scabies lay eggs on a person's skin, causing skin reactions and inflammation. When a female scabies buries an egg under the skin, the person's reaction is exacerbated, such as an itch, which is scabies. Symptoms: itching, pain, pus, skin irritation.
